Global edible oil consumers have no option but to pay top dollar for supplies after Indonesia's surprise palm oil export ban forced buyers to seek alternatives, already in short supply due to adverse weather and Russia's invasion of Ukraine.

The move by the world's biggest palm oil producer to ban exports from Thursday will lift prices of all major edible oils including palm oil, soyoil, sunflower oil and rapeseed oil, industry watchers predict. That will place extra strain on cost-sensitive consumers in Asia and Africa hit by higher fuel and food prices.

"Indonesia's decision affects not only palm oil availability, but vegetable oils worldwide," said James Fry, chairman of commodities consultancy LMC International.
